Product Overview

The Delta DPA01NR-P is a multifunction pressure sensor designed for reliable pressure measurement and control. Compact and versatile, it offers digital output, analog output, and optional RS-485 communication — making it suitable for automation systems, instrumentation panels, and industrial gas-pressure monitoring applications.

Key Features

• Measures gauge pressure (non-corrosive gas) within ±100 kPa range (–100 to +100 kPa)
• Built-in outputs: 2 × digital (NPN/PNP) + 1 × analog output (4–20 mA or 1–5 V) for versatile integration
• Supports standard pressure units: kPa, bar, psi, mmHg, inchHg, kgf/cm² — user-selectable
• 3-color LCD display (green/orange/red) for normal, setup, and alarm/status modes for easy visibility of pressure status
• Fast zero-reset and parameter copy function (reduces setup time when deploying multiple sensors)
• Multiple output response time settings (from 2 ms up to 5000 ms) for flexible control/monitoring behavior
• Shock- and vibration-resistant construction (suitable for demanding industrial environments)
• Compact size and light power requirement (12–24 V DC supply) — easy to integrate into control panels and automation systems
